THUMB-HOLD FOR BOOK-LEAF TURNING.

Application filed December 30, 1918.

To all whom it may concern:

Be it known that I, Rc'nonrn lllonssnL, f citizen of the United States, and a resident of Toledo. in the county of Lucas and State of Ohio, have invented a certain new and useful Thumb-Hold for Book-Leaf Turning; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accon'ipanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention has for its object to provide a means for holding the leaves of a book while consecutive leaves are being delivered. It provides a, means whereby the thumb of the user ofa book having my invention, will have a better hold on the leaves that are bent back, than is provided by the trimmed edges of the leaves of a trimmed book, and which will at the same time enable the user, by manipulation of his thumb, to permit the leaves to escape consecutively from his than can be obtained by an edge trimmed book. The inventionis particularly advantageous when used in connection with books such as magazines having deckle edge.

In the production of my invention the edge of the book, that is, that portion of the book that is formed by leaves, is gauged out so as to form a surface located substantially at right angles to thefront and back of the book. The surface is substantiall perpendicular to the front and back of the book and is preferably a curved surface which will substantially fit the curvature of the thumb.

The invention may be modified by those skilled in the art yvithout departing from the spirit thereof. I have illustrated the invention inthe accompanying drawings as applied to a book having a deckle edge, such as a magazine.

In the drawings Figure 1 illustrates a book or magazine having the invention. Fi 2 is a top view of the magazine, and

1 in the figures is a book or a magazine havin a deckle edge. The leaves are gouged at 2 so as to form, when the book is closed, a curved smooth surface located substantially at right angles to the trout and the back of the book. In turningthe leaves of the book they are curved backward. that is. from the user, in the manner well known. while the thumb is placed in the gouged portions of the leaves of the book. The smooth gouged edges form a large area of contact between, not only the edges of the leaves of the book and the thumb, but also between minute portions of the leaves that border the curve formed by the gouge, and the thumb. This greatly increased area of contact that extends along the surface of the thumb enables the user to better grip the leaves and so manipulate the thumb as to perspective view of the magamore readily deliver the pages or leaves in succession. Moreover, this will be done with greater accuracy, that is, by reason of the gouge, the thumb may be more readily manipulated so as to delivergthe pages in succession without skipping the pages.

The advantage of the invention is particularly useful in connection with a mnguzine having untrimmed edges, for-by my invention the gouge will be readily formed in the edge of the magazine, inasmuch as but a very short cut is made in the edge and the utility of readily turning the pages of such a book is apparent inasmuch as. in order to turn the pages of such a book, each page must be picked at the top or rubbed over with the thumb or finger of the user in order that they may be turned consecutively.

I claim:

1. A rough edged hook having a recess in its front edge formed by cutting the edges of the leaves of the book the recess extending through the body of the book and hav mg a smooth surface located substantiallv 2. A rough edged book having a recess in book when the book is closed and forming its front edgeextending through the body a thumb hold for delivering the pages in of the book and formed by cutting the edges succession. 10 of the leaves of the book, the recess having In testimony whereof, I have hereunto 5 a curved smooth surface extending through signed my name to this specification.

the body of the book end substantially at right angles to the front and the back of the RUDOLPH MUESSEL.
